RsaPrivateKey

class RsaPrivateKey(val publicKey: RsaPublicKey, privateExponent: ByteArray, p: ByteArray? = null, q: ByteArray? = null, dp: ByteArray? = null, dq: ByteArray? = null, qInv: ByteArray? = null) : PrivateKey

An RSA Private Key.

Parameters

publicKey

the corresponding public key.

privateExponent

the private exponent (d) as an unsigned big-endian byte array.

the first prime factor (optional).

the second prime factor (optional).

the first factor CRT exponent d mod (p-1) (optional).

the second factor CRT exponent d mod (q-1) (optional).

qInv

the CRT coefficient (inverse of q) mod p (optional).

Properties

val d: ByteArray

The private exponent (d) as an unsigned big-endian byte array.

val dp: ByteArray?

val dq: ByteArray?

isDestroyed

open override val isDestroyed: Boolean

true if this key has been closed/destroyed, false otherwise.

javaPrivateKey

val RsaPrivateKey.javaPrivateKey: ERROR CLASS: Symbol not found for RSAPrivateKey

modulus

val modulus: ByteArray

The modulus (n) of the public key as an unsigned big-endian byte array.

val p: ByteArray?

privateExponent

val privateExponent: ByteArray

publicExponent

val publicExponent: ByteArray

The public exponent (e) of the public key as an unsigned big-endian byte array.

publicKey

open override val publicKey: RsaPublicKey

val q: ByteArray?

qInv

val qInv: ByteArray?

Functions

open override fun close()

Securely zeroes out the private key material in memory and marks this key as destroyed. Subsequent cryptographic operations or property accesses on this instance will throw IllegalStateException.

destroy

fun destroy()

Cryptographic alias for close.

duplicate

open override fun duplicate(): RsaPrivateKey

Creates an independent duplicate of this private key with its own lifecycle and memory buffer. The returned key must be closed independently.
